This hype was nothing compared to 2017 end hype ,xrp goes into insane rally mode and we have see one of the biggest manipulation in major altcoin .it might be possible that they have payed for the listing but xrp has good exchange volume so it is not difficult for it get into coinbase as they have searching for new coin to add on.
I, too, without a difference in rumors and even methods of promoting a coin. I like Ripple, I expect to arrive 50-110% this year.
